How Mirvac is achieving safety through simplicity – An interview with Zenergy

Creating an engaging health and safety culture is challenging enough within an organisation. When you have a business that connects with as many as 200 contractors at a single time, any issues are multiplied considerably.


Zenergy’s strategy to identify and promote influential leaders across industry has led me to Grant Medlock from Mirvac to understand how they had addressed this challenge and what their changes mean for the wider industry.


Mirvac is a company with a large construction division across Australia, meaning it requires a health and safety program that not only encompasses its direct employees, but the many contractors and sub-contractors that work on its sites as well.


As the National HSE Manager – Construction at Mirvac, Grant Medlock was instrumental in the design and the rollout of the Mirvac Risk Assessment Cards (MRAC) program. Grant ran us through some of the challenges Mirvac faced, and the solutions it pioneered to set new safety standards in Australia’s construction industry. For Grant, it was important that the company could continue to support its employees across all construction sites.

Developing people as a company grows

The reason Mirvac was able to evolve its health and safety programs effectively is because it was aware of how its position in the market was changing. By realising how quickly its construction department was growing, the company was then able to work out what this expansion would impact the most: its people.

“We concentrated on developing our people.”


For Mirvac, expanding construction operations meant more active sites with an increased number of contractors and people working for the firm. Rather than just thinking broad, Grant and his team acknowledged health and safety needed to be accessible on an individual level, so that’s where they began.


“We concentrated on developing our people, strengthening their understanding of the basic HSE requirements, helping to assist and develop their own individual knowledge and understanding,” he explained.


Mirvac’s reputation for quality is intrinsically linked to its relationships with contractors. As the efforts of these professionals are such an essential part of the business, any major health and safety change had to be adaptable to this diverse workforce.


“For us, the focus on our subcontractors, the way they perform their work, what it is they’re doing, how they’re doing it and again the culture within their own groups is important,” Grant says.


As relationships in this sector stretch from major companies down to small businesses, any new system would have to support their safety as well.

Mirvac’s solution

The misconception that health and safety is all about red tape and paperwork is simply no longer the case, a fact that Grant and his team proved with the MRAC program. The initiative is the second wave of the “Work Safe Stay Safe” campaign the firm premiered in 2014.


“It’s a simple, easy to use, easy to follow card system with high-quality visuals and simple control measures,” Grant said.


“We call it ‘What good looks like’, so when a contractor is about to put together something for a particular job they can take an MRAC from a booklet, read through it, and it guides them through the controls we expect them to have in place.”


“It guides them via a photograph or an image of what we expect from a scene and how we expect it to look.”


Grant notes that the MRAC rollout is now about much more than just health and safety. Various contractors have given positive feedback, and there’s plenty of evidence to suggest that it’s raised the overall standards of work on Mirvac construction sites as well.



MRAC and Work Safe, Stay Safe, will soon be available in app form, an update that will bring even greater accessibility to the format.

Changing the industry through simple processes

With the MRAC system, Mirvac is proving that compliance doesn’t have to be complex for employees and contractors to use or managers to monitor.


“By making them simple, by giving them imagery and by making the terminology easy to reflect upon, it’s had a good uptake,” Grant said. “For us, it’s about not over complicating things, but rather ensuring that the information we supply to our sub-contractors is concise and accurate.”


The beauty of introducing the systems to the various contractors and sub-contractors Mirvac engages with is that this spreads the message to the rest of the industry. These businesses don’t just work for Mirvac, and by making their own workspaces safer, they’re directly raising the safety profile of the wider construction sector as well.


“Safety is universal,” Grant explained. “We’re open about what we do, it’s about improving our sites and the rest of the industry.”

“If other companies were to see this as an incentive or an idea that they want to move forward with then we would be happy to have helped the industry.”


Mirvac’s MRAC rollout is proof that changing a safety environment doesn’t depend on complexity. Instead, by making health and safety simple to understand and easy to execute, the company is changing the way wider industry keeps safe at work.

Two years after the release of the groundbreaking 2022 Everyday Respect Report, Rio Tinto has undertaken a thorough Progress Review to assess its ongoing cultural transformation. As one of the world’s largest mining companies, Rio Tinto has been working to create a safer, more inclusive workplace culture that fosters respect, productivity, and innovation. The 2024 Progress Review highlights significant strides made, ongoing challenges, and areas requiring further attention. The Journey Towards Cultural Transformation Cultural change is a multi-year effort that requires consistent leadership, structural support, and engagement across all levels of an organization. Since launching its Everyday Respect initiative, Rio Tinto has embedded this agenda into its core business strategy, focusing on reducing bullying, sexual harassment, and racism in the workplace. Key Progress Areas: Increased Awareness and Open Conversations: The public release of the original report acted as a catalyst for change, encouraging more employees to speak up and engage in discussions about respect. Stronger Leadership Commitment: Leaders are playing a more proactive role in championing Everyday Respect, with a focus on psychological safety and inclusive leadership. Enhanced Training and Education: Programs such as Everyday Respect Training and Purple Banners have been widely implemented to build awareness and response capabilities. Facility Upgrades and Safety Improvements: Investments in workplace infrastructure have improved the physical environment, making it more inclusive and conducive to employee well-being. Greater Workforce Diversity: There has been a notable increase in gender and cultural diversity across teams, fostering innovation and improved workplace dynamics. Ongoing Challenges and Areas for Improvement Despite progress, resistance to change remains an obstacle, particularly among certain groups. Survey data indicates that while improvements have been perceived in many areas, instances of bullying, sexual harassment, and racism persist. Key focus areas include: Building Stronger Buy-in: Engaging those who are resistant to cultural change, particularly male employees, to foster a collective commitment to Everyday Respect. Enhancing Reporting Mechanisms: Increasing trust in reporting systems to ensure that employees feel safe and supported when raising concerns. Strengthening Frontline Leadership: Providing additional training and tools to equip supervisors and managers with the skills needed to drive culture change at all levels. Maintaining Momentum: Ensuring that Everyday Respect remains a priority in the face of organizational changes and external pressures. Looking Ahead: Staying the Course The findings from the 2024 Progress Review reaffirm Rio Tinto’s commitment to long-term cultural transformation. While meaningful progress has been made, continued efforts are needed to sustain positive momentum and address persistent challenges. As one employee noted: “ Change is definitely happening, and it will get hard at times. We can’t back away ... I’m here at Rio Tinto because I want to see through this change. We need to stay the course. ” With ongoing leadership, engagement, and strategic initiatives, Rio Tinto is on the path to embedding Everyday Respect across all facets of its global operations, ensuring a safer, more inclusive, and more productive workplace for all employees.
